Hand-held cutting blades are used in a wide range of applications. In addition to production and processing, there are many companies that use electrician temporary work. Do you think it is safe to use a resin EN12413 cutting discs that is very common and simple to operate? In fact, the hand-held cutting piece looks ordinary. Once the cutting piece is broken, the power of attack is not small! Accident case On the morning of January 17, 2017, Wang went to the construction site as usual. He came to work and picked up his familiar hand-held cutting piece to start work. Unexpectedly, the accident happened. The grinding wheel that is spinning at a rapid speed suddenly breaks, and the lobes carry a huge inertia. They fly to Wang with lightning speed. The lobes of the cutting piece directly penetrate the eyes of Wang and are embedded in his brain. He smashed his face into two halves and eventually died. Hand-held cutting blades have the following major risk hazards 1. Object blows (cutting pieces break and blow out to hurt people) 2. Electric shock (the power cord is damaged and the metal part is leaking) 3. Mechanical damage (cutting of the cutting piece in operation) 4. Fire, explosion (sparks generated by cutting or grinding ignite flammable materials and hazardous chemicals causing fire or even explosion) Handheld cutting sheet considerations 1 must use a cutting piece with a protective cover; 2 Class II hand-held power tools should be used. Class II power tools use double insulation or reinforced insulation to prevent electric shock. The nameplate has a “back” type mark; 3 Check whether the cutting piece is in good condition before use; the grinding wheel that is damp, deformed, cracked, broken, edged or touched with oil or alkali should not be used. Moist cut pieces should not be used by themselves. The grinding wheel and the padding pad should be installed securely and the nut should not be too tight. 4 When operating, the operator must wear protective glasses and helmets correctly. When using the angle grinder, hold the hands with both hands. It is strictly forbidden to wear the workpiece. 5 During operation, personnel should not stand in front of the cutting piece and should stand on the side; if the working time is too long and the temperature rises, it should be stopped and then cooled naturally before operation. 6 When using the flat abrasive cutting disc, remember that the force is too strong. The blade should be held steady and then pressed by the switch. Slowly contact the sanding surface and apply force. It is forbidden to suddenly touch the rotating grinding wheel to the grinding surface, or to press the grinding head to grind it hard. It is not allowed to press the grinding head on the grinding surface and then press the switch to avoid collapse of the grinding wheel and to injure people.
add to favorites Main factors of deformation and cracking caused by wire cutting Pc  
No Picture
1.related to the structure of the part The concave and convex dies of the narrow and long shape are easy to be deformed, and the magnitude of the deformation is related to the complexity of the shape, the aspect ratio, and the width ratio of the cavity to the frame. standard cut off wheel for metal.The more complicated the shape, the larger the aspect ratio and the ratio of the cavity to the frame width, and the larger the deformation amount of the mold. The law of deformation is the middle of the cavity, the punch is usually warped, and the quenching cavity with complex shape and clear angle is prone to cracks at the sharp corners, and even prone to bursting. The frequency of occurrence is related to the composition of the material, the heat treatment process, etc.; the cylindrical wall thickness is easier to deform if it is cut on the inner wall, generally changing from a circular shape to an elliptical shape. If it is cut into the gap, it will easily burst when it is cut through; the deep slot cut from the outside of the part is easy to deform, the law of deformation is the mouth adduction, the magnitude of the deformation and the depth of the notch and the material properties. related.
2 related to the hot processing process When the die blank is forged, the forging temperature is too high or too low, and the final forging temperature is low; the final forging temperature is too high, the grain grows, the cooling rate is too slow after the final forging, and the die blank with the precipitate of the net carbide is precipitated. The forging blank annealing is not carried out according to the spheroidizing annealing process, and the spheroidized pearlite exceeds 5 grades; the quenching heating temperature is too high, the austenite grains are coarse, the material toughness is lowered, and the brittleness is increased; the quenched workpiece is not tempered in time. Parts that are not tempered.,
3 related to the machining process The larger concave die has a large area in the middle and has not been hollowed out beforehand. Due to the large volume in the frame, the frame size will produce a certain deformation; Where there is no shape starting point in the blank, the hole has to be cut from the outside of the blank, no matter how the tempering and shape of the punch is, it is generally prone to deformation, especially the quenching part is severely deformed, even in the cutting; For the ground parts after heat treatment, there are no grinding wheel particle size, feed amount, cooling method and other process requirements. After grinding, there are parts such as burns and micro cracks.
4. Related to the wire cutting process The wire cutting path is improperly selected, and it is easy to produce deformation. The clamping method of the workpiece is unreliable, and the selection of the pinch point is improper, and the deformation is easy to occur; the electric gauge is improperly selected and cracks are easily generated
add to favorites Effect of grinding conditions Pc  
No Picture
1 grinding wheel speed The increase in the linear speed of the grinding wheel reduces the maximum depth of cut of the abrasive particles, reduces the cross-sectional area of ​​the chips, and increases the number of cuttings and the heat of grinding. These two factors increase the amount of infarction, but when the linear velocity of the grinding wheel reaches a certain level (for example, up to 50 m / s), the amount of infarction of the grinding wheel is greatly reduced.cut off disc for stainless steel
2 workpiece speed The effect of workpiece speed on wheel infarction levels is closely related to other elements in the cutting conditions. The line speed of the workpiece is doubled and the infarct volume of the wheel is increased by a factor of three. This is because the higher the workpiece speed, the shallower the penetration depth of the abrasive grains, and the smaller the cross-sectional area of ​​the chips, which corresponds to the hardening of the characteristics of the grinding wheel, and thus it is easy to cause wheel infarction.
3 grinding method In fact, cut-in grinding is more severe than longitudinal grinding of the infarct. During the cutting and grinding process, the contact area between the grinding wheel and the workpiece is large, and the abrasive cutting edge rubs on the same wear scar several times. The slurry enters the grinding zone, and the heat is high during the grinding process, which easily forms infarction. The longitudinal grinding contact with the workpiece data is the side edge of the grinding wheel. When the wear surface is increased to a certain level, the abrasive particles are broken and broken under the action of the grinding force, and self-sharpening is completed. Most abrasive particles work in a sharp state, making the grinding force and grinding heat relatively low. At the same time, a substantial portion of the grinding force and the heat affected zone of the grinding can exit the workpiece in the direction of longitudinal grinding, thereby reducing the likelihood of chemical bonding.
4 grinding temperature cut off disc for stainless steelsupplier show that Any factors that increase the heat of grinding and increase the grinding temperature during grinding can exacerbate the infarction of the wheel. The infarction method is mainly bone cement infarction, and of course, diffusion infarction.
5 grinding wheel dressing speed The dressing speed of the grinding wheel has a significant effect on the infarction. When the dressing speed of the grinding wheel is low, the working surface of the grinding wheel is flat, and the number of effective grinding per unit area is increased, so that the cross-sectional area of ​​the cutting chips becomes small and the number of cuttings is increased, and infarction is easily generated. When the dressing speed of the grinding wheel is high, the working surface of the grinding wheel becomes thicker, the number of effective abrasive grains is reduced, the concave portion appears on the outer surface of the grinding wheel, acts as a hole, the chip is easily washed away, and the sintered material is easily dropped.
6. Grinding fluid Different grinding fluids have a great influence on the grinding effect. At present, ordinary emulsions contain a large amount of mineral oil and oily additives. After dilution, it is an oil-in-water emulsion white liquid with a small specific heat capacity and thermal conductivity and is very intense during rubbing. Adhesive wear and diffusion wear are easily formed between the grinding wheel and the workpiece, so that the grinding wheel is subjected to impact, the grinding force is increased, and finally the premature crushing and falling of the abrasive grains are caused, so that the grinding ratio is lowered.

The use of CNC tool grinding disc low price disc for metal directly affects the normal use of CNC tools. A small part can sometimes cause the whole project to fail. Therefore, we will introduce the automatic trimming and compensation method of CNC tool grinding machine diamond cutting piece today. . The development of automatic CNC grinding technology has put forward high requirements for its supporting equipment. As one of the supporting technologies, the online automatic cutting blade trimming technology must meet the needs of modern CNC grinding technology, and it is developing in the direction of high precision, ultra-stable and fully automatic control. As a highly efficient grinding tool, 6 inch es cutting disc are widely used in the processing of hard materials such as cemented carbide, ceramics and CBN. The dressing and automatic compensation method of the diamond cutting piece determines the performance of the fully automatic CNC grinding machine, which largely determines the performance and service life of the cutting piece. Diamond cutting chip dressing principle The diamond cutting piece dressing method is an important factor affecting the grinding performance of the cutting piece. The reasonable selection of the dressing method will directly affect the surface quality and grinding precision of the workpiece. Currently used diamond cutting blade dressing methods include: online electrolytic dressing, EDM cutting, cup cutting, electrolytic-mechanical compounding and laser trimming. Since the cup-shaped cutting piece dressing method is simpler and easier to implement than other dressing methods, the diamond cutting piece is automatically trimmed by the GC cup-shaped cutting piece dressing technique. The dressing of superhard abrasive cutting discs for diamond cutting sheets is usually divided into two stages: shaping and sharpening. Shaping is a micro-cutting of the cutting piece. The purpose is to remove the shape error and surface defects of the cutting piece after the initial installation, and to ensure the geometric accuracy of the cutting piece. The sharpening is due to the passivation of the cutting piece after working for a period of time. In order to make the cutting micro-blade protrude the bonding agent and have a proper height, a sufficient space for the chip is formed between the abrasive grains, and the number of effective abrasive grains per unit area is as large as possible. . Method for dressing bowl type diamond cutting piece with GC cup-shaped cutting piece The actual geometrical relationship between the GC cup-shaped cutting piece and the bowl-shaped diamond cutting piece and the movement form are shown in Fig. 1. The bowl-shaped diamond cutting piece and the GC cup-shaped cutting piece grinding belt are completely staggered and fitted, and are respectively rotated at a certain rotation speed, and the rotation speed of the dressing wheel and the cutting piece is positioned at 8:1. The dressing wheel is fixed, and the 14 inches cutting disc is trimmed and fed in the axial direction, so that the GC cup-shaped cutting piece and the bowl-shaped diamond cutting piece form mutual abrasive grinding. Through the grinding of the end faces of the two cutting pieces, the diamond cutting piece passivation abrasive grains are removed to form a chip space, and the surface of the diamond cutting piece is re-sharpened to achieve the purpose of dressing.

China cut off disc The cutting piece is widely used in our life due to its impact resistance, high tensile strength and bending resistance. However, the phenomenon of the film that occurs when using the cutting piece affects our normal use, and sometimes it is doubtful why the film appears.
1. The temperature difference is too large when the cutting disc is produced. Since the cutting piece should have a certain cooling time period at the end of the hardening and heat preservation to satisfy the uniform release of stress; at this time, if the temperature of the furnace is too high or the temperature difference changes too much, the cooling change of the grinding wheel will not be synchronized, so the deformation of the grinding wheel appears. It is.
2. Hardening furnace kiln eliminates hardening and humid atmosphere All hardening furnaces, whether box furnaces or tunnel kiln, must consider intake and exhaust when designing the furnace. Due to the release of a large amount of exhaust gas (mainly only ammonia gas, water vapor) during the hardening process, if these exhaust gases cannot be discharged in time, they will be re-adsorbed by the pores during the cooling process, causing the grinding wheel to be odorous and soft.
3, hardening stable low The low stability of hardening means that due to the dual influence of environment and raw materials, the hardening temperature is not provided in time when the seasons alternate or the temperature and humidity change significantly. The hardening is high, which means that the hardening curve has been adjusted, but when the stability is happy, the weather is dry, and when the weather is dry, the hardening of the hardening is not easy.
4, the hardening curve is short This mainly means that under certain conditions, the low-temperature drying time of the hardening curve is short, and the heating rate is too fast in the heating stage. ad.high performance cutting disc

Compared to traditional processing technology, there are obvious benefits to drinking. 12 inches cut off wheel .This not only cuts the functionality, reduces costs, but is also more environmentally friendly. It does not cause a lot of residue residues. Water treatment is a practical and versatile, efficient cold cutting. Water jet refers to the treatment of water pressure rising to a sufficiently high level (above 200 MPa), so that water with high kinetic energy can penetrate chemical fibers, wood, leather, rubber, etc., in certain mixing ratios and high-speed abrasives, including ceramics, stone, glass, metal, alloy and other solid materials. The correct operation of the water jet cutting operation is very high. The final cut is selected. What should I pay attention to? 1. During the cutting process, the operator and unrelated personnel should remain in the device for a certain period of time. Cut small and light blankets and use a specific method to avoid cutting during this process. 3. The need to ensure that the flat cut at the beginning of the work, to prevent damage to the pipes and cause cut-sand safety accidents. 4. If the workpiece was struck during the cutting process, other objects will be blocked to correct. 5, the procedure for replacing the batch process superimposition spray must be the first switch High pressure, high pressure, or closed, the second remaining high pressure water is removed and cooked. 6. If you use water jet cutting, different pressure peaks should be selected on different materials.12 inches cut off wheel more better. 7. Using a jet cutter process, pay attention to the seal water jet status supercharger and high pressure pipe. 8. When there is an accident, high pressure water is in the high-pressure system. After the call is made, the remaining high pressure water is emptied. Therefore, the time should not be interrupted from the beginning. When the power is switched on, the high pressure water remains low. Except for. 9. The operator should always check the flashing status of the device's operating status display. 10. Pay attention to the equipment when driving the blank.

There are many factors affecting the cutting performance of high performance cutting discThe ultra-thin cutting wheel is mainly used for precision grooving and cutting, and has a large grinding depth, a small feed speed, a large contact area between the grinding wheel and the workpiece, and a narrow slit. High metal removal rate, high grinding precision, good surface quality and high material utilization.

1. Ultra-thin cutting disc abrasive grain size, thin abrasive cutting disc for metal use fine particle size, and the thinner the general thickness of the abrasive grain will be correspondingly thinner, the surface quality is good. However, the finer the abrasive grain size, the corresponding cutting sharpness decreases, and the feed rate is correspondingly reduced to accommodate the machinability of the abrasive grain size. The cutting depth of the ultra-thin cutting wheel is generally determined by the user according to the cutting part.
Generally, the law of cutting the grinding wheel by the deep-cutting and slow-feeding grinding method is that the integral-type cutting wheel has the advantages of thin thickness, fine grain size, high dimensional and shape precision, light weight, and is generally used under high speed conditions. The general speed is 5000-40000 rpm. The base type cutting grinding wheel is mostly thick (0.5-2mm), large in diameter, coarse in grain size and low in precision, and is generally used under conditions of lower rotation speed and large depth of cut. The general speed is 3000-10000 rpm.
2. Balance affects cutting performance. When the cutting piece jumps large, the cutting will swing back and forth, making the cutting width larger. The consumption of the material is large, and the consumption of the cutting piece is naturally large. When the cutting piece has a large radial runout, the vibration is large at the initial stage of cutting, which tends to cause the cutting piece to fall off, affecting the strength and cutting, and automatically trimming after cutting, and the overall influence becomes small.
3. The thickness of the cut piece affects the cutting performance. The thickness of the cutting disc is high, and the slit width consumes the cutting piece; when the strength is guaranteed, the thin flat cutting disc is recommended, which not only saves the cutting piece material but also saves the cut material;

MILWAUKEE (AP) — The Milwaukee Brewers put Xavier Cedeno on their roster for the NL Championship Series against Los Angeles , adding another left-hander to their deep bullpen for the matchup with the Dodgers’ power-packed lineup.Cedeno had a 1.13 ERA in eight innings over 15 games after he was acquired in a trade with the Chicago White Sox on Aug. 31. Cedeno replaces slick-fielding outfielder Keon Broxton, who homered in Game 3 of the NLDS sweep against Colorado.Left-handed hitting Max Muncy has a team-high 35 homers for the Dodgers. Two more left-handers, Cody Bellinger and Joc Pederson, are next with 25 each.“We made a choice basically to add another pitcher, because it could be a seven-game series,” manager Craig Counsell said. “We add another left-hander that we think matches up well in kind of a number of situations. So we add extra potential outs. And then the sacrifice is we’re losing a baserunner, a defender, and we’re losing a hitter.”The Dodgers are sticking with 12 pitchers and 13 positions players, but made one change from the Division Series. They switched left-handers for the NLCS, with Julio Urias taking Scott Alexander’s roster spot.The hard-throwing Urias had no record and didn’t allow a run in three games this season. He returned to the big leagues in mid-September after missing more than a year following surgery on his left shoulder.“The value of Julio to come in and get one to four or five outs David Robertson Jersey , I think that for us with our bullpen construction, we feel comfortable with that,” manager Dave Roberts said.Alexander was 2-1 with a 3.68 ERA and three saves this season. He made one appearance in the NLDS against the Braves, pitching a scoreless ninth inning in Game 3. CHICAGO (AP) — While David Bote is learning about the major leagues, baseball is learning about the rookie, too.Like be really, really careful when he steps to the plate in a big spot.Bote struck again on Friday, connecting in the 10th inning for another game-ending home run that sent the Chicago Cubs over the Cincinnati Reds 3-2 for their third straight victory.The 25-year-old Bote, an 18th-round pick in the 2012 draft, got behind 0-2 before driving Raisel Iglesias’ next pitch deep to left field with one out. He flipped his batting helmet off as he approached his smiling teammates and tried unsuccessfully to sidestep a water-cooler shower before stepping on home plate.“I don’t know what was in that Gatorade bath. It smelled horrible ,” a laughing Bote said. “But I mean it feels great, so it’s fun.”Bote created quite a splash earlier this month, hitting a bottom-of-the-ninth, two-out grand slam on a Sunday night that beat Washington 4-3 on Aug. 12. Each of his five career homers has either tied the game or put the Cubs in front.“Just hunting spots on pitches and I was able to get a barrel on it,” he said.Iglesias (2-2) had made seven straight scoreless appearances. Jesse Chavez (4-2), the sixth Cubs reliever, pitched a scoreless inning for the win.“That was an extremely well-played game, well-pitched game,” Reds manager Jim Riggleman said.Daniel Murphy homered in the eighth for NL Central-leading Chicago, and Javier Baez had a run-scoring single in the sixth. Alec Mills pitched 5 2/3 innings of one-run ball in his first major league start.Last-place Cincinnati wasted a solid performance by Matt Harvey in its fourth loss in five games. Harvey struck out six in 5 1/3 innings after he was reportedly claimed off waivers by the contending Brewers Luis Severino Jersey , only remaining with the Reds when they couldn’t work out a deal.“I didn’t know what to expect,” Harvey said. “There were some nerves, I guess, some different feelings coming through this morning. … I’m glad I’m still staying here the rest of the season.”Harvey is 6-5 with a 4.14 ERA in 18 starts after he was acquired in a trade with the New York Mets, salvaging his season after a rough start. But he is eligible for free agency this winter and isn’t expected to stay with the Reds.“He’s really good. If you want something good, you have to give up something, you know?” Riggleman said. “Obviously, nobody wanted to give up enough. In their eyes, they probably felt it was enough. We certainly didn’t think it was enough.”Bote and Albert Almora Jr. struck out swinging before Murphy drove the next pitch from Jared Hughes over the wall in right for his first homer since he was acquired in a trade with Washington on Tuesday.The crowd of 37,760 roared as Murphy rounded the bases , and the veteran second baseman acknowledged the cheers by popping out of the dugout for a curtain call.But Cincinnati responded with Eugenio Suarez’s leadoff drive on a 2-2 pitch from Pedro Strop in the ninth, tying it at 2. It was Suarez’s 29th homer, extending his career high, and just the second blown save for Strop since closer Brandon Morrow was placed on the disabled list last month.NOT QUITE THERECincinnati jumped in front on consecutive doubles by Mason Williams and Phillip Ervin leading off the second. It looked as if Williams had connected for his second homer, but a replay review showed the ball caromed off the front of a post holding up the basket in left-center.Williams had to go back to second, but he scored anyway when Ervin followed with a liner into the gap in left-center.HMMMMMMills struck out eight while filling in for Mike Montgomery, who is on the disabled list with left shoulder inflammation. Montgomery threw a bullpen session before the win and is scheduled for another one on Sunday.“We’ll wait ’til Sunday to figure out what we want to do next,” manager Joe Maddon said. “But Alec really permitted us to think different thoughts.”Reliever Dillon Maples was optioned to Triple-A Iowa to make room for Mills on the roster.TRAINER’S ROOMReds: 1B Joey Votto (lower right leg) was scheduled for more work on Friday and Saturday. He could come off the disabled list on Sunday. “I’m getting more and more encouragement from him and the trainers,” Riggleman said.Cubs: OF Jason Heyward rested for the second straight day. Maddon said his left ankle has been bothering him. … 3B Kris Bryant (left shoulder inflammation) hit in the cage. “He felt really good about what he did,” Maddon said. … Morrow (right biceps inflammation) had an MRI on Thursday. “Everything’s fine Aaron Judge Jersey ,” Maddon said. “He’s still in his process of getting back.”UP NEXTReds right-hander Luis Castillo (7-10, 4.86 ERA) and Cubs left-hander Jose Quintana (10-9, 4.36 ERA) pitch on Saturday. Castillo is coming off a solid start against San Francisco, striking out nine in 6 2/3 innings in an 11-4 victory on Sunday. Quintana is winless in his last three starts, but he pitched four-hit ball into the sixth inning in a no-decision at Pittsburgh in his previous outing.
add to favorites Ore crusher is a coarse crushing machine Pc  

Ore crusher is a kind of coarse crushing machine which has a wide application in the ore beneficiation process and other industries. This mining machine is commonly used in the medium and fine crushing process. In order to properly select and use the ore crusher, we will give you a brief analysis.

The main advantages about the gold ore crusher:

1. Continuous operation, high production capacity and low power consumption. Compare with the jaw crusher, its production capacity is 2 times higher than the latter, while the power consumption of per ton of ore is 0.5-1.2 times lower than the jaw crusher;

2. Stable operation, less vibration and lighter basis weight. The basis weight of the ore crusher is 2-3 times of the equipment weight. To the jaw crusher, it is 5-10 times of the equipment weight.

3. The ore can be fed directly into this quarry crusher machine which doesnt need the ore bin and feeder. The jaw crusher should be equipped with the ore bin and the feeder to ensure the feeding uniform, which greatly increases the cost.

4. The ore crusher can be started easily, while the start of jaw crusher needs the auxiliary tool to turn the heavy flywheel.

5. The content of sheet products is less.

The disadvantages of ore crusher:

1. The height of ore crusher is 2-3 times higher than the jaw crusher, which increases the construction cost of the factory.

2. It is not suitable for the crush of the wet and sticky ores.

3. The maintenance of this machine is complex and the check is inconvenient.

4. The total investment of this machine is high.
